lose one's heart to

lose height

Despite it being a biplane, I really did need very low power settings and improbably high speeds to make it lose height.

Just one second later, 44 seconds before the collision, the Swiss air traffic controller instructed the Tupolev to lose height as quickly as possible, contrary to the automatic warning he had just received.

Paul made a pass, then circled back round for his landing, as the revs dropped we lost height then glided in for a smooth landing.

Origin

The medieval word loose is related to Old English lose and loss, and also to the ending -less, signifying ‘without’. The sense ‘immoral, promiscuous’ dates from around 1470 from the original sense ‘free from bonds’. The term a loose cannon sounds as if it should be centuries old, perhaps from the days of warships in Napoleonic battles. In fact, the first recorded uses are from the late 19th century, and the phrase only really gained currency in the 1970s. That said, it does come from the idea that a cannon which has broken loose from its mounting would be a particularly dangerous hazard on any ship, but especially a wooden one. See also fast
